Compatibility Profiles needs more clarity
The Compatibility Profiles section in crypto-refresh-02 is lifted pretty much wholesale from RFC 6637. It doesn't have much in the way of an explanation of why it exists.
Ángel noted on the list:
An introduction should be added after "16. Compatibility Profiles" and before "16.1" explaining what are Compatibility Profiles and why would they be interesting / needed.
I think the section might have made more sence in 6637 ("Compatibility Profiles" in "ECC for OpenPGP" is different than "Compatibility Profiles" in "OpenPGP"), so some context is needed. Who needs to care about these profiles? are they only relevant for ECC? do we need other Compatibility Profiles?
